I am not sure if anyone was watching but News Channel 4 in Greenville, SC has been airing a series on barefoot running. Go to this link and the latest barefoot running story should pop up.
Scott Murr is in the story and he is the coauthor of the book Run Less Run Faster. He has been doing some barefoot running along with shod running. He believes that the barefoot running helps to strengthen your feet. I liked the story and it all is very positive towards running barefoot. Check it out if you get a chance!
